Useful information
i This Operator's Manual describes all
models and all standard and optional
equipment of your vehicle available at the
time of publication of the Operator's
Manual. Country-specific differences are
possible. Please not ethat your vehicle may
not be equipped with all features
described. This also applies to safety-
related system sand functions.
i Read the information on qualified
specialist workshops: (Y page 25).Overview of climat
econtrol systems Important safet
ynotes
Observ ethe settings recommende donthe
following pages. The windows could
otherwise fog up.
To preven tthe windows from fogging up:
R switch off climate control only briefly
R switch on air-recirculation mode only
briefly
R switch on the cooling with air
dehumidification function
R switch on the defrost windshield function
briefly, if required
The automatic climate control regulates the
temperature and the humidity of the vehicle
interior and filters out undesirable
substances from the air.
Automatic climate control/dual-zone
automatic climate control is only operational
when the engine is running. Optimum
operation is only achieved with the side
windows and panorama roof with power tilt/
sliding panel closed.
The residual heat function can only be
activated or deactivated with the ignition
switched off (Y page 132).
i Ventilate the vehicle for abrief period
during warm weather, e.g. using the
convenience opening feature (Y page 84).This will speed up the cooling process and
the desired vehicle interior temperature
will be reached more quickly.
i The integrated filter filters out most
particles of dust and soot and completely
filters out pollen. With dual-zonea utomatic
climate control, gaseous pollutantsa nd
odors will also be reduced. Aclogged filter
reduces the amoun tofair supplied to the
vehicle interior .For this reason, you should
always observe the interval for replacing
the filter, which is specified in the
Maintenance Booklet .Asitdepends on
environmental conditions, e.g. heavy air
pollution, the interval may be shorter than
stated in the Maintenance Booklet.
i It is possible that the dehumidification
function of the climate control system may
be activated automaticallyanh our after the
SmartKey has been removed. The vehicle
is then ventilated for 30 minutes. 122
